[TR] Early TR4 lens question

[spook01 at comcast.net (spook01@comcast.net)]

My TR4 needs a rear tail lamp lens and I see two different part numbers.  One 
is L669, the other L779.
>From the photo, they appear identical, but my car came with the L669.
Is this just a p/n change, or are the lens different?
Info will be appreciated!
